lNDIVIDUALIZING CUT-OUT FOR PRlNTlNG-TELEG RAPHS.

SPECIFICATION forming part of Letters Patent No. 477,665, dated. June 28, 1892.

Application filed February 10, 1892. seen no. 420,937. (a model.)

To all whom it may concern:

Be it known that I, SAMUEL RUSH' LIN- VILLE, a citizen of the United States, residing at the'cityof Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improve-. ments in Individualizing Cut-Outs for Printing-Telegraph Systems, of which the following is a specification.

Mypresent invention is applicable in whole or in part to a single or double line system of printing telegraphy that is operated by sources of electric energy, and transmitters included in a single or double line, and either having the sources or electric energy located at thetransmitters or having the sources of electric. energy and pole-changing alternating and extra battery devices located at central or terminal stations, whether the type-wheels ate the electric devices and individualizin'g,

of receivers are arrested with a closed or open line circuit.

The principal object of my present invention is to provide simple, durable, and efficient means for enabling an operator at any transmitting-instrument connected in line with other transmitters and receivers to select one or more of the receivers to the exclusion of the others for receiving and recording amessage, whereby secrecy in the transmission of messages issecured.

My present invention, stated in general terms, comprises a'telegraph-line, a series of receiving-instruments provided, respectively,

with" type-wheel shafts adapted to include electrical devices responding to abnormal currents and adapted to operate individualizing cut-out mechanism, and one or more transmitting-instruments provided with apparatus for electrically controlling the type-wheel's and transmitting abnormal currents to actucut-out mechanism of the reeeiversto include thereby the desired receiving instrument or instruments in line.

My invention may be carried into eifect b'y short-circuiting the electro"- magnets which directly control the rotationv of the typewheels or by interrupting the local circuitswhich 'control the type-wheels of v anyor all the receivers included. in a line by 'ine'ans of individualizing cut-out mechanismactuated either by. electro-magnetsin local or line battery circuits closed through said electromagnets by relays or electro-magnetshrespondin-g only to abnormal currents in said line, so that an operator at any transmitter is enabled not only to short-circuit without interrupting the line the electromagnetic devices controlling the type-wheels of any receivers which he requires to cut out, but also to restore said circuits when desired. A

The nature and general characteristic, features of my invention will be more'fully un-' derstood from the followin g description, taken in connection with the ace mpanying drawings, forming part hereof, and in which-I Figure l-is a view of a central or terminal station and a combined receiving and transmitt ing instrument, showing alternating and arresting devices located at the central or terininal station andalsoshowingtheprintingand transmitting devices and circuit-switches and individualizing devices located at the combined transmitters and receivers and also illustrating, diagrammatically, all the circuits. Fig. 2 is a view of a combined transmitting and receiving instrument, showing the batteries and transmitting devices for alternating and increasing thestrength of the current in the line, a neutral relay in saidline, printing devices actuated by a local battery, typewheels actuated by a polarized armature respending to alternating currents in the line,

and individualizing devices and circuits. Fig.

apparatus, and the cut-out circuits, and also illustrating in dotted lines a neutral relay,

which may be disposed in the line to operate the cut-out magnet by a local battery; and Fig. 7 is a view of a transmitting and receiving instrument, showing alternatingdevices,

a circuit-breaking key, a neutral relay, and a pole-changer for sending abnormally-strong pulsations of the required polarity from the entire battery to actuate the neutral relay.

For the sake of a description of my present invention reference v'villbe made to a system? of printing-telegraphy in which the batteries,- alternating, arresting, and other devices, and'j the combined transmitter and receiving circuits shown in Fig. 1 are substantially the" same as are described in the Letters Patent of the United States No.450,630, dated April- 21; 1891, and granted to Samuel R. Linvilleand Louis F. Hettmansperger, and the circuit switches, individualizin g apparatus,and short circuits for rendering the receiverinoperative will be described in connection with such a system of printing-telegraphy,but it must be borne in. mind that my invention is applicable to other types or systems of telegraphy.

' In the drawings, a is a shaft supported in bearings a and adapted to be rotated step by When the circuit through the electro-magnet- A is broken, the armature of will be retracted by the spring a, and the pawl a. being held in contact with the ratchet-wheel a by the spring a engages the next tooth ot the ratchet-wheel (t it being understood that the detenta prevents retrograde inovementof the ratchet-wh eela On the shaft a are rigidly mounted adisk b and a hub b, of conducting material, insulated from said shaft. The periphery of each of the disks 1) appertaining to the respective rcceivers in line is notched at a zero-point 12 corresponding with one of the teeth ot-the respective ratchet-wheels a and also at an additional point P), corresponding with one of the successive teeth of the respective ratchet-- wheels a For example, all the ratchetwheels have as many teeth as there are re- (settling-stations, and the notch 1) min alignalignnient with the second succeeding tooth.

'ment withf fthe first succeedingftooth of the" ratchet-wheel in instrument No.1, and isin in instrument No. 2, and so on in thesncceeding, instruments.

Assuming, for thesake of a,further description, that all the circuit-preserving springs batall the instruments are in engage-t men-twith the notches b and that all theratchet-whecls a are rotated synchronously tooth' by tooth, then the receiver No. 1 is included in line when all the'ratchct-Wheels a have advanced one step, because the notch b is shift:

ed into position for permitting the projection on the spring bflto drdp into the notch b on the disk I), thus breaking circuitwith the disk b and permitting the circuit-spring b. to contact with the circuit-spring'b Inthe meanwhile the other receivers are cut out'of line because the projections on the springs b ride upon the disks 1), and thus short-circuit'the line through the hubs b and their accessories. In the individualizing apparatus at station N052 the projection on the spring 1) drops into the second notch b in the disk I) when all the ratchet-wheels a have advanced two steps,

because the notch 11 will then have been brought beneath the projection, and at the I succeeding stations the projections of the re spective springs will drop into the notches b whenever the ratchet-wheels have advanced a number of steps equal to the number of the respective stations.

It will hereinafter be shown that any or all receivers in line can be short-circuited through the instrumentality of the shaft 0, by causing abnormal pulsations in the line and closing and breaking the circuit through the electromagnets A.

Although theterminal-station circuits and .devices illustrated'i n Fig. 1 are well known 'andare fully described in the patent hereinbefore mentioned, still a brief description of the same will now be given.

The pulley-c is frictionally connected with the shaftc, on which are mounted an escape ment-wheel c, an alternator D, and a unisonspiral e. The pulley c is constantly turned by any suitable contrivance or source of power. The battery Q is closed through the pole-changer F and alternator D,one electrode of the batteryQ being connected through the coils of the relay G. The battery Q is adapted to be closed in parallel with the battery Q. The electro-magnet F of'the polechanger isenergized byalocal battery q when the armature-lever g of the relay G contacts 'withlits front stop 9, and when it contacts with its .back stop 9 this .circuit is broken and the line-battery Q is connected with the. pole-changer F by closing the circuit of the positive electrode at. the contacts on the lever g and spring of the relay G. From the pole-changer F the electrodes are connected to the springs bearing on the alternator D, and thence one electrode goes to earth and the other is directed to line through the electro-magnets of the polarized relay I'l, thence to the circuit-preserving spring b of the receiving-instruments, which spring must be in the position shown clear of contact with the disk b, thence through spring 19 thence through the electro-magnets of the polarized relay I at the receiver and through the magnets of the relays J and K to the circuit-spring Z, the insulated hub-Z on the type-wheel shaft liarm and brush Z ,-to line-contacts of the sunflower l key-arm m of the keys M, upper contact m, and to earth or to line and through 'the other receivers to earth.

.The escapement electro-magnets l, energized by the circuit of a local 'battery q, closed through contacts of the polarized relay I, control the type-wheel of the receiver. The paper-carriage and printing-pallet are actuated by the ele'ctro-magnet N, included in the circuit of the local battery g closed at the back contact of the relay J, when the linecircuit is broken by any of the keys corresponding to the contacts on the sunflower Z in the row Ofkeys M. A key M short-circuits the sunflower by closing the line at contact m through the resistance m to earth or to line through other receivers and then to .earth. The relay K is adjusted to respond only to currents in the line stronger than the currents which actuatethe relay J. The lever n of the electro-magnctN is mechanically connected with the unison-latch n of the re ceiver and also with the unison-latch 0 of the -the spring s will contact with the spring 8 and cause it to break contact with the spring 8, thereby breaking the circuit of the local battery g through the electro-magnet N and closing the circuit through'the eIectrO-mag net A.

' hen the line-circuit is closed through all combined-transmitters and receivers, as is normally the case, the lever or relay G at the terminal station will remain incontact with its front stop 9', and the armaturef 1' will be held in contact with the electro-magnets of the pole-changer F. Under such "circumstancesthe' alternator D w ll run con- 'tinuously in a well-known manner, the escapement-lever' c and pallets '0 being constantly vibrated by the electro-magnets C, re-

sponding alternately to the currents of the battery (1 closed by the contacts of the polarized relay H, the said relay being actuated:

through successive reversals of current by the alternator D'until the alternatorand the type-wheels of all the receivers in line are arrested in unison. When a key in the row 'scription.

of keys M at any receiver is depressed, the line-circuit is broken and the armatures g and f of the, relay G and' pole-changer 1* fall away. The line-batteries Q and t are now in parallel, as has been hereinbefore described, and the circuit of the battery (1 is closed 'by the contact f on the pole-changer lever f and contact f through the unison electro-magnet P. At the sametimcthe lever It of the relay K at the receivers closes thecircuit of the battery (12 through the magnet N, thereby simultaneously releasing the unison-latches of the alternator and of all the receivers in line; 7 v

The line-battery Q is alone in circuit with the relay G at the terminal station. The resistance m between the key M and earth or' line must be such that the current in line from'the battery Q will not cause the electromagnets-of the relayG at the terminal sta- I tion to overcome the resiliency of the adj ust-.

tug-spring g of said relay. The line-circuits stand reversed through the pole-changer F when its armature f is retracted in consequence of a break in the line-circuit at one of the rows of keys M, and when the line is closed by th'ekey M through a resistance m by depressing the key M, so as to shortcircuit the sunflower, and the break in; the

line at the row of keys M, the current of the combined batteries Q and Q, and of the same polarity as last actuated, the polarized relays at the terminal stationand at the receivers will go to line without actuating said relays or the neutral relay' G at the terminal station. The operation. of the individualizingcut-out mechanism in connection with an automatic system, such as described, will be clearly understood from the following de receivers connected in'line and provided'with circuits and devices, substantially such asare illustrated in Fig. 1.

-Anoperator, say,' at receiverNo. 1 wishes to communicate with receiver No. at and to short-circuit the operative magnets of all the other receivers.'-rlhe operator releases the unison-latches and presses a key in the row of keys M, calleda font-out key,and adapted to arrest all the type-whecls at the cut-out position,,whereupon the arms .9

on the t 7 rewheel shafts Z M of all the receivers will collide with the springs 8 closing the local circuits ofthe local batteries (1 at the receivers through the electro-magnets A and breaking said circuits through the electro inagnets N. The operator, then holding down the cut-out key to maintain the break in the line through the suntiower'of his receiver, causes'a sufii-' cient number of abnormal'makes and breaks in line by closingand breaking the short air-- 'cuit through the. keyM'yand resistance m to rotate all-the individualizing-shafts a and devices thereon to the unison position. At this position all the respective disks 1) have notches 15?, as has been. hereina-b'ove explained, and the line-circuits areall in normal cou- However, there must be several nection through the electro-magnets directly or indirectly controlling the type-wheels of the respective receivers in line. It may be remarked that in such position the unisonlatches 0 lock the shafts a, and it is necessary to release these latches 0 before the shafts mayagain be rotated. The keys M and M that were previously Operated are released and all thetype' wheels automatically run to unison with the alternator and are locked in such position bytheir unison-latches n and o. During'the operation the circuits of the local batteries (1 are restored to the electro-magnets N by the movement of the arms sflon the type-wheel shafts Z to aposition out of contact with the spring 8 A key (not shown) corresponding to the unison position is then pressed, so that the line is interrupted and the unison-latches e, n,'and o of the alternator and of all the receivers in line are' again released, as previously descfibed, in order to permitof the rotation of the shafts a 0'7 The operator nextarrests all the type; wheels at the cut-out position by holding down the cut-out key.' In this position the individualizing electro-magnets A are again included in the circuit of the batteries g at all the receivers. The operator then causes all the shafts a to advance four steps by maintaining the break in the line through the sunflowerby' holding down the cut-out key and at the same time seuding'strong currents over the line to actuate the relay K by making and breaking the line four times through the short circuit-key M and resistance m In this position of the shaft on the spring 12 will enter the notch 29 and clear the disk b only at receiver No. 4, and at all others the springs Z2 will ride in contact with the metallic disks 1), thereby cutting such instruments out of line. At receiver No.4: the polar relayI will be in the line-circuit through the circuit-pro serving springs b and b and the main line, as shown in Fig. 1, while at all the other receivers the contact between the springs b and b is interrupted, because the springs I) ride on and contact with the disks 1), and thus the line is connected to the springs b through the hubs 1), whereby the polarized electro magnets I are short-circuited. The operator may now move his individualizing-shaftto the No. 1 position or employ a switch to restore the circuit through his polarized relaymagnets in a manner well known to electricians, and receivers. Nos. 1 and4 will then be in operative communication with each other to the eicclusion of all the other receivers in line. If the disks bat two or more receivers have notches at corresponding radial positions, all such receivers to the exclusion of the others may be brought into operative connection with each other.

I do not limit my invention to the specific circuits and devices hereinbefore described, as it is obvious that the resistance m in the line short circuit may be varied or omitted.

vices is not material, and that a cylinder with contacts and insulations and springs bearing thereon, or numerous other Well-known devices operating to transfer the line-current from one. circuit to another, may be substi- Moreover, the polarized relay I and local battery g at the receivers may be omitted, in

tire-magnets controlling the type-wheels, and to cut out a receiver it is of course necessary to short-circuit these magnets. consisting of numbered contacts and insulations in dial form operating in connection with a pivoted contact-arm adapted to sweep over said contacts may be employed in lieu of the key M.'- A disk a, Fig. 3, rigidly se-.. cured to theshaft a placed in relation'to the typc-wheel shaft 1, as shown, and having a unison-notch a and a. notch a, through which an arm a on the type-wheel shaft 1 may freely pass, may be employed. In this instance the notch a, is arranged to correspond in radial position'with the he reinbefore-described notches. b on ,the disks b, so that the disks a l op ate to arrest the typeout positions, and this result may be accomplished ,either with or without the employment of the line short-circuiting devices by manipulating the keys in the manner hereinbefore explained. The application of my invention' to numerous we ll-known systems of at central stations or transmitters connected electrically with receivers'at all stations will be apparent to electricians skilled in the art, and it may be remarked that it is immaterial an arm on the type-Wheelshaft or by an arm moving synchronously therewith.

The following adaptations will be briefly described:

In Fig. 2 is shown a combined transmitter and receiver provided with a type-wheel magnet I, included in the line-circuit, and with a local battery g The alternating devices F of these instruments are connected to the electrodes of a part only of a line-battery Q and operate when vibrated totransmit alternating currents through the relay J and the typewheel magnets I to actuate andsetthe typewheels.

depressed operates toinelude the entire battery Q in the line-circuit, the polarity of the current to line being determined by the position in which the alternatingdevices F are arrested. 'W hen the type-wheel L is arrested at the cut-out'position, the arm 8 pressing-the circuit-spring s o'ut'of contact with the spring s; transfers'the circuit of the battery g from the magn et 11 to the magnet A, and said circuit may then be closedthrough the front contact f of the relay J by sending strong pulsations That the form of the circuit-controlling de ,t'oiine by alternately dcpressing'and releasing l the circuit-presenving key B. By this means which case the line-circuit energizes the elec- 'tuted for the disk-b and springs Z), 11 and b. v

A pulsator wheelshafts of all the receivers in line at cutprinting-telegraphy having transmitters only I whether the circuit-switch s is controlled by printing-magnet N, included in the cireuitof' a The circuit-preserving key R when l) with the disk Z) in the manner above described, whereby the type-wheel magnets I are short-cireuited by a line closed through a resistance m.

In Fig.4 the receiving and the transn'iitting devices are similar to those illustrated in Fig.

2; but the line-circuit, instead of passing.

through the coils of the typc-wheelelectro magnets I, is connected to the coils, of the.

electro-magnet of a polarized relay Land the type-wheel electro-magnets I are energized by the alternating currents of a local battery q", closed by the contacts-of said relay. In this case the individualizing apparatus opcrates to short-circuit the polarized relay 1 by interrupting the line between the springs b and b and closing it around said relay through the disk I), huh 1), spring I), and resistance 772 there arresting the operation of the type-wheel electro-magnets I. It is apparent that the line between the tongue of the polarlzed relayIaud the type-wheel electro-magnets I may be interrupted by the individnalizing-springs b b and b, or the local battery (1 may be short-circuited in any wellknown manner by the devices employed to short-circuit the polarized relay instead of short-circuiting said relay, as shown.

In the circuits and apparatus illustrated in Fig. 5 the transmitting devices are similar to those illustrated in Figs. 2 and 4 and hereinbefore described. The neutral relay responding only to strong currents in line is omitted and the printing electro-m'aguet'N and the individ ualizing magnet A are in the line-circuit, and thefilatter must be adjusted to respond only to abnormally-strong currents from the entire battery Q The switch or circuit.- prcserving-spring s, actuated by an arm s on the type-wheel shaft 1*, operates to interrupt the line-circuit through the printing' electro-magnet N and to close said circuitthrough the individualizing electro-magnet- A. The polarized relayI may then be shortcircuited through the spring bfldisk b, spring I), and resistance m by rotating the individualizing devices by means of strong currents, as hereinbefore described. I

In the circuits and apparatus illustrated in Fig. 6 the polarized relay is omitted, the typewheel magnets I are included in the 1iueciredit, and the printing and individualizing electro-magnetsN and A are adapted to be included iu'said circuit, the printing electromagnet N responding to prolonged pulsations in the line-circuit and the individualizing electro-magnet A responding to abnormally ing of the line, as by a key t.

strong pulsations, it being understood that short weak pulsations operate the type-wheel electro-magnets I. The iudividualizing apparatus is adapted to short-circuit the type wheel cleetro-magnets when the type-wheels are arrested at the cut-out position, ashereinbcforc fully described. The dotted lines in Fig. 6 indicate a relayJ responding to strong pulsations and adapted to be included in the line, if desired, in which case the individualizing electro-magnct A may be energized by the local battery closed through the front stopj of said relay. The linecircuit could in such case be permanently connected through the coils of the printing electro-magnct N, and the circuit-switch s and circuit connections therefrom to the electro-magnet A might then be omitted.

- In Fig. 7 the transmitting devices are adapted to send alternating currents of a portion of the battery Q to line, and in case the transmitter runs automatically in a well-known manner by sending alternating currents through escapement-m'agnets I, controlling the movement of a power-impelled shaft Z", and the transmitter is arrested through the interruption of the line-circuit by the break- IIowever, the devices hereinbefore described for sending strong pulsations must be modified, for example,in the following manner: A current of the same polarity as ized relays I or escapement electro-magnets 1 must be sent when the line is closed around the break at the key u otherwise the transmitter would-start and the 'type-wheels of the receivers would be moved. To obviate this difficulty,a pole-changer F or equivalent device mnst be employed to send abnormallylast energized the polar-Y strong pulsations of the desired polarity from the entire battery Q to actuate the neutral.

relay J, The operation of short-circuiting the polarized relay I at the receiver whenthe type-wheel is arrested at the cut-out position has been hereinbefore described with reference to similar circuits in Fig. 4.

My invention is applicable to systems of telegraphy operating by direct currents of the same polarity, since, instead of a neutral relay responding only to strong currents, a polarized' relay arranged to contact on one point by sending reversed normal currents may be included in line in a Well-known manner operating to close and break the circuit through the indi'vidualizing electro-magnets.

I desire itto be understood that my invention comprises the generic feature otshortcircuiting or rendering inoperative the devices cation to all systems of printing telegraphy.

Having thus described the nature and ob- JPt'l-S of my invention, what I claim as new,

and desire to secure by Letters Patent, is-
